The insulation coating layer is made of a composition containing 100 parts by mass of a base polymer (A) and 100 to 250 parts by mass of a non-halogen flame retardant. The polymer (A) contains 70% to 99% by mass of an ethylene-vinyl acetate copolymer (a1) containing an ethylene-vinyl acetate copolymer having a melting point of 70° C. or higher, and 1% to 30% by mass of an acid-modified polyolefin resin (a2) having a glass transition point of −55° C. or lower. The polymer (A) contains 25% to 50% by mass of a vinyl acetate component derived from the copolymer (a1). The outer coating layer is made of a composition containing 100 parts by mass of a base polymer (B) and 150 to 220 parts by mass of a non-halogen flame retardant. The polymer (B) contains 60% to 70% by mass of a linear low-density polyethylene (b1), 10% by mass or more of an ethylene-vinyl acetate copolymer (b2) having a melt flow rate of 100 g/10 min or more, and 10% to 20% by mass of a maleic acid-modified polyolefin (b3).
